In other words, after returning to the Yamunā, Akrūra saw Balarāma turned into Śeṣa Nāga and Kṛṣṇa turned into Mahā-Viṣṇu. He saw the four-handed Supreme Personality of Godhead, smiling very beautifully. He was very pleasing to all and was looking toward everyone with a merciful glance. He appeared beautiful with His raised nose, broad forehead, attractive ears and reddish lips. His arms, reaching to the knees, were very strongly built. His shoulders were high, His chest was very broad, and His neck was shaped like a conchshell. His navel was very deep, and His abdomen was marked with three lines.
(Krsna Book).

While Akrūra was offering his prayers to the Supreme Personality of Godhead, the Lord disappeared from the water, exactly as an expert dramatic actor changes his dress and assumes his original feature. After the viṣṇu-mūrti disappeared, Akrūra got out of the water. Finishing the rest of his ritualistic performance, he went near the chariot of Balarāma and Kṛṣṇa and was struck with wonder. Kṛṣṇa asked whether he had seen something wonderful within the water or in space.
(Krsna Book).

After saying this, Akrūra immediately started driving the chariot, and by the end of the day they reached the precincts of Mathurā. As they rode from Vṛndāvana to Mathurā, all the passersby along the way who saw Kṛṣṇa and Balarāma could not help but look at Them again and again. In the meantime, the other inhabitants of Vṛndāvana, headed by Nanda and Upananda, had already reached Mathurā by going through the forest, and they were awaiting the arrival of Kṛṣṇa and Balarāma in a garden. Upon reaching the entrance to Mathurā, Kṛṣṇa and Balarāma got down from the chariot and shook hands with Akrūra. Kṛṣṇa informed him, "You may go home now because We shall enter Mathurā later, along with Our associates."
(Krsna Book).

On hearing this, the Supreme Personality of Godhead, Kṛṣṇa, replied, "Akrūra, I shall surely come to your home with My elder brother, Balarāma, but only after killing all the demons who are envious of the Yadu dynasty. In this way I shall please all My relatives." Akrūra became a little disappointed by these words of the Supreme Personality of Godhead, but he could not disregard the order. He therefore entered Mathurā and informed Kaṁsa about the arrival of Kṛṣṇa, and then he entered his own home.
(Krsna Book).

After Akrūra's departure, Lord Kṛṣṇa, Balarāma and the cowherd boys entered Mathurā to see the city. They observed that the gate of Mathurā was made of first-class marble, very well constructed, and that the doors were made of pure gold. There were gorgeous orchards and gardens all around, and the whole city was encircled by canals so that no enemy could enter very easily.
(Krsna Book).

When the news spread that Kṛṣṇa, Balarāma and the cowherd boys were within Mathurā City, all the inhabitants gathered, and the ladies and girls immediately went up to the roofs of the houses to see Them. They had been awaiting the arrival of Kṛṣṇa and Balarāma with great anxiety, and in their extreme eagerness to see Kṛṣṇa and Balarāma, the ladies did not dress themselves very properly. Some of them placed their clothes in the wrong place. Some anointed their eyes on one side only, and some wore ankle bells only on one leg or wore only one earring. Thus in great haste, not even decorated properly, they went to see Kṛṣṇa from the roofs. Some of them had been taking their lunch, but as soon as they heard that Kṛṣṇa and Balarāma were in the city, they left their eating and ran to the roofs.
(Krsna Book).

Some of them were in the bathroom taking their baths, but without properly finishing their baths, they went to see Kṛṣṇa and Balarāma. Some were engaged in feeding their children breast milk, but they put their babies aside and went to see Kṛṣṇa and Balarāma. Passing by very slowly and smiling, Lord Kṛṣṇa immediately stole their hearts. He who is the husband of the goddess of fortune passed through the street like an elephant. For a very long time the women of Mathurā had heard about Kṛṣṇa and Balarāma and Their uncommon characteristics, and they were very much attracted and eager to see Them. Now when they actually saw Kṛṣṇa and Balarāma passing on the street and saw Them sweetly smiling, the ladies' joy reached the point of ecstasy. When they actually saw Them with their eyes, they took Kṛṣṇa and Balarāma within their hearts and began to embrace Them to their fullest desire. Their bodily hairs stood up in ecstasy.
(Krsna Book).

They had heard of Kṛṣṇa, but they had never seen Him, and now their longing was relieved. After going up on the roofs of the palaces of Mathurā, the ladies, their faces joyful, began to shower flowers upon Kṛṣṇa and Balarāma. When the brothers were passing through the streets, all the brāhmaṇas in the neighborhood went out with sandal water and flowers and respectfully welcomed Them to the city. All the residents of Mathurā began to talk among themselves about the elevated and pious activities of the people of Vṛndāvana. The residents of Mathurā were surprised at the pious activities the cowherd men in Vṛndāvana must have performed in their previous lives to be able to see Kṛṣṇa and Balarāma daily as cowherd boys.
(Krsna Book).

While Kṛṣṇa and Balarāma were passing in this way, They saw a washerman and dyer of clothing. Kṛṣṇa was pleased to ask him for some nice clothing. He also promised that if the washerman would deliver the nicest dyed cloth to Him, the washerman would become very happy, and all good fortune would be his. Kṛṣṇa was not a beggar, nor was He in need of clothing, but by this request He indicated that everyone should be ready to offer Kṛṣṇa whatever He wants. That is the meaning of Kṛṣṇa consciousness.
(Krsna Book).

The washerman then began to instruct Kṛṣṇa and Balarāma: “My dear boys, in the future don’t be so impudent as to ask for things which belong to the King. Otherwise, You will be punished by the government men. They will arrest You and punish You, and You will be in difficulty. I have practical experience of this fact. Anyone who unlawfully wants to use the King's property is very severely punished.”
(Krsna Book).

After this ghastly incident, the employees of the washerman immediately dispersed, leaving the clothing. Kṛṣṇa and Balarāma took possession of it and dressed according to Their choice; the rest of the clothes were offered to the cowherd boys, who also used them as they desired. What they did not use remained there. Kṛṣṇa, Balarāma and the boys then proceeded along the main road. In the meantime, a devotee-tailor took the opportunity of service and prepared some nice clothes from the cloth for Kṛṣṇa and Balarāma. Thus being very nicely attired, Kṛṣṇa and Balarāma looked like elephants dressed with colored clothing on the full-moon day or the dark-moon day.
(Krsna Book).

After dressing nicely, Kṛṣṇa and Balarāma went to a florist of the name Sudāmā. As soon as They reached the precinct of his house, the florist immediately came out and with great devotion fell down on his face to offer his respectful obeisances. He offered a nice seat to Kṛṣṇa and Balarāma and asked his assistant to bring out flowers, betel nuts and pulp of candana. The florist's welcome greatly satisfied the Lord.
(Krsna Book).

The florist, Sudāmā, was greatly pleased within his heart by seeing Kṛṣṇa and Balarāma in his place, and thus, as his choicest desire, he made two exquisite garlands of various flowers and presented them to the Lord. Kṛṣṇa and Balarāma were very much pleased with his sincere service, and Kṛṣṇa offered the florist His salutation and benedictions, which He is always prepared to bestow upon the surrendered souls. When the florist was offered benedictions, he begged from the Lord that he might remain His eternal servant in devotional service and by such service do good to all living creatures.
(Krsna Book).

After leaving the florist's place, Kṛṣṇa and Balarāma saw a hunchbacked young woman carrying a dish of sandalwood pulp through the streets. Since Kṛṣṇa is the reservoir of all pleasure, He wanted to make all His companions joyous by cutting a joke with the hunchbacked woman. Kṛṣṇa addressed her, "O tall young woman, who are you? Tell Me, for whom are you carrying this sandalwood pulp in your hand? I think you should offer this sandalwood to Me, and if you do so I am sure you will be fortunate." Kṛṣṇa is the Supreme Personality of Godhead, and He knew everything about the hunchback. By His inquiry He indicated that there was no use in serving a demon; she would do better to serve Kṛṣṇa and Balarāma and get an immediate result of the service.
